Clement Street: your questions answered
Will you come out to Clement Street?
Yes. Clement Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Farningham Road station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you work on commercial floors?
Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor when you ask for a quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Where are you based?
Mr Mastic is based in Crawley. We cover Clement Street and the rest of Kent, along with the rest of our area.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Why does the gap under my skirting keep coming back?
Floors shrink and settle, especially in the first year or two and through the heating season opens the gap. Rigid fillers split, so we use a flexible sealant.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Floor joint sealing in Clement Street, done properly
Concrete floors in warehouses and units have joints that take heavy wear. Each is resealed with a floor-joint product suited to what runs over it. Typical jobs include skirting that has pulled away from the floor and cracked caulk along skirting in bathrooms and kitchens, across concrete floor joints, tiled floors and thresholds.
Around Clement Street, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Different surfaces, different methods
Thresholds
A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.
Concrete floor joints
We clean concrete joints out thoroughly before sealing. Backing goes in where the depth needs controlling.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Sweep along the edges of the floor
- Act on grout cracks that run in a straight line
- Use a well-wrung mop rather than flooding the floor
- Use furniture pads near skirting
Keep off the joint for the time we give you. Light foot traffic is usually fine sooner than wet cleaning or wheels.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning or an afternoon for most homes. In a small place like Clement Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- The joint is vacuumed clean and backing fitted where needed.
- We apply the sealant in a colour that suits the floor.
- We tool it neatly and tell you when it can be walked on and cleaned.
Before we arrive
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Joints and finishes in Clement Street homes
Floors around Kent run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Sutton-At-Hone Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For landlords with property near Farningham Road station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as Church of Saint Paul, joints in its floors, skirtings and thresholds need resealing as they wear.

Quotes for floor joint sealing in Clement Street
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The product the joint needs
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- The type of property
- Access, such as stairs, a lift or height
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Why act early in Clement Street
The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. In a small place like Clement Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Why book with us
- An ARBOMaster approved applicator
- Old sealant always removed completely
- We agree the colour with you first
- Neat joints and a tidy finish
